General description

The LPC11U1x are a ARM Cortex-M0 based, low-cost 32-bit MCU family, designed for

8/16-bit microcontroller applications, offering performance, low power, simple instruction

set and memory addressing together with reduced code size compared to existing 8/16-bit

architectures.

The LPC11U1x operate at CPU frequencies of up to 50 MHz.

Equipped with a highly flexible and configurable Full Speed USB 2.0 device controller, the

LPC11U1x brings unparalleled design flexibility and seamless integration to today’s

demanding connectivity solutions.

The peripheral complement of the LPC11U1x includes up to 32 kB of flash memory, 6 kB

of SRAM data memory, one Fast-mode Plus I2C-bus interface, one RS-485/EIA-485

USART with support for synchronous mode and smart card interface, two SSP interfaces,

four general purpose counter/timers, a 10-bit ADC, and up to 40 general purpose I/O pins.
